Can you use concrete blocks for footings?

Asked By: Roman Luštrik Date created: Jun 13, 2022

Ensure a solid footing. Footings should be a minimum of twice the width of the concrete block (i.e., a typical 8x8x16 block would require a 16-inch wide footing) and extend below the frost line. NOTE: it is important to check local building codes for construction requirements in your area.

Why are iron nails of railway tracks fixed over wide wooden or concrete sleepers?

Asked By: Simulant Date created: Jun 25, 2022

Iron rails are fixed over wide wooden or concrete sleepers to reduce pressure received from the train by increasing the area of contact, because if surface area increases pressure decreases and vice-versa, they also transfer the loads to the ground underneath.

Why are railway tracks laid on large sized concrete sleepers?

Asked By: Andrey Deineko Date created: Jun 19, 2022
